It will also show key val-ues for the Devices, such as radio strength, current values, logging interval and how many logs the Device holds.When a Device’s button is pressed, the background of the Device cell in the Device List will turn grey for approximately 10 seconds. The Class ID will also become 255 during this time. This feature is designed to enable a Device to be identified in the app physically.If a Device’s cell is left swiped, it will expose a button “blink” that if pressed will cause the LED on the De-vice to blink. This feature is designed to enable the Device to be identified from inside the app.The battery level is in % of volts. 100% means voltage is approximately 3 volts. The battery will need to be changed if the voltage drops below 2 volts or approximately 70%. As a safety precaution to prevent the RAM of the Device from being corrupted, if the battery drops below 70% the Device will power down until the battery is replaced.
Temperature, Humidity & Dew Point Bluetooth Sensor and Logger User Guide 1.20Metrics for logged data over the last 24 hours (only shown if the logging interval is greater than 15 minutes)Metrics for logged data since logging beganTime and date of last downloadThe Device Details screen will provide further information in relation to a particular Device. The Current Values are the current readings of the sensors. The historic metrics are derived from logged data. It may be that the Current Values appear to exceed or be lower than historic metrics simply because the Current Values are only logged every Logging Interval.The First Log Date is the same as the Reference Date and is the time and date of the first log. This then sets the timestamp reference for each and every logged value stored in the Device. If there is no Refer-ence Date then on a Download the app will try to work out the Reference Date but this can be inaccu-rate. It is advisable that a User sets the Reference Date as a first step in setting up the Device. IMPOR-TANT: Changing the Reference Date will cause stored sensor data to be deleted and logging to restart.

NOTE: Changing this deletes stored logs and logging starts againGoes back to DeviceDetails screen3. Commands of the iOS appEach of these commands will be explained more fully in the following sections.
Temperature, Humidity & Dew Point Bluetooth Sensor and Logger User Guide 1.203.1 Name ChangeThe default name of the Device is the first 8 digits of its MAC address, which can also be found on a stick-er on the back cover of the Device. This can be changed to any other name not exceeding 8 characters in length. Any characters in excess of the 8 limit will be omitted.The Device’s name will appear in the advertisement packet of the Device itself. That is to say the name is not local to the iOS smartphone/tablet, it is actually embedded in the Device and will be seen by all users.3.2 Logging IntervalThe logging interval determines the frequency of logging. The minimum value is 60 seconds (or 1 min-ute) and the maximum value is 24 hours. The value should be entered in as seconds.Changing the logging interval deletes any stored logs and logging restarts. This is due to any change in the logging interval potentially compromising the integrity of the timestamps for the logs since the timestamps are calculated on the assumption each log has the same time interval from the Reference Date.3.3 Sensor IntervalThis sets the frequency the sensor is polled for displaying the current sensor readings. It does not affect the Logging Interval. Changing this does not delete any stored logs. The default is 20 seconds.NOTE: Shortening the sensor interval can have a negative impact on battery life.
Temperature, Humidity & Dew Point Bluetooth Sensor and Logger User Guide 1.203.4 Reference DateThe Device uses a real time clock to log each reading at the Logging Interval. The Reference Date and Time is the time and date of the first log which is then used to calculate the time and date of each subse-quent log. Reference Date and Time is entered as a 10 digit number and represents the time of the first log to the minute.For example to enter 11.42pm on Thursday 7 September 2017 the 10 digit number would be:1709072342.It is advisable when setting up the Device for a logging task, one of the first steps is to set the Reference Date and Time.NOTE: Changing the Reference Date and Time will delete the stored data and logging will begin again.In the iOS App the Reference Date and Time able to be en-tered in a more user friendly format than typing in 10 digits since the app will con-vert the current date and time into the 10 digit number for you
Temperature, Humidity & Dew Point Bluetooth Sensor and Logger User Guide 1.203.5 Alarm 1 Set and Alarm 2 SetThe Device is able to keep track of temperature or threshold breaches in real time by a user setting either or both Alarm 1 and Alarm 2. If either or both of these alarms are set, at each Logging Interval if the temperature or humidity being logged breaches any of the alarms a flag is raised in the advertisement packets being transmitted by the Device and when the Device is scanned by the app a red triangle with a number next to it representing the count of how many times the temperature or humidity has breached the set values will appear in the Device List screen.The breach count maximum is 255, and any further breaches beyond this number will not be counted.The alarms are set by entering the threshold number as a whole unit (no decimal points) in the relevant units of measure then selecting whether the breach will occur if the metric is above or below this num-ber.Enter the threshold number FIRST before selecting whether the threshold is > or < than. This number is a whole number (no decimal points).If this is left blank then the relevant alarm will be turned offNOTE: The alarms apply on a forward logging basis only. That is to say that if an alarm is set and there is already logged data breaching the alarm stored in the Device, there will be no warning indicator shown.3.6 Clear AlarmsThis will clear the alarms and turn them off.
Temperature, Humidity & Dew Point Bluetooth Sensor and Logger User Guide 1.203.7 Airplane ModeTo comply with U.S. FAA and international carrier regulations, the Devices have an Airplane Mode that will allow them to continue logging but prevent them from radio transmitting. This works by toggling Air-plane Mode On or Off. When Airplane Mode is On the Device will continue transmitting for 60 seconds and will then go to sleep but will continue to log data and keep track of alarm information and telemetrics. If the Device’s button is pushed during this time the Device will transmit for 60 seconds before going back to sleep. To take the Device out of Airplane Mode it is necessary to cause the Device to transmit since the app is unable to communicate with the Device if its radio is asleep.Not only does Airplane Mode allow the Device to continue logging while in flight, Airplane Mode can also be set when it is necessary or desirable to extend the battery life of the Device on long journeys (such as when logging sea journeys). In Airplane Mode the Device consumes substantially less power since the radio consumes most of the power of the Device. Therefore if it is not necessary for the Device to continu-ously transmit consider putting it in Airplane Mode to conserve battery.TIP: Airplane Mode can extend the battery life of the Device and over 2 years of logging is possible with just a CR2032 coin cell. Consider putting the Device in Airplane Mode if it is not necessary for the Device to continuously transmit.3.8 Transmit PowerThis allows the transmission power of the Device to be changed to conserve battery life. The default set-ting is +4dB which is the maximum. Choose from one of the other settings (either 0dB and -4dB). Please note reducing the transmission power can affect the operational range of the Device.3.9 Clear Stored DataThis clears any stored logs, the alarms and any telemetric data stored in the Device. It does not change other settings such as the Name, Reference Date and Time and the Logging Interval.3.10 Reset DeviceThis performs a factory reset of the Device and is the same as a long button push performed on the Device itself.
Temperature, Humidity & Dew Point Bluetooth Sensor and Logger User Guide 1.203.12 Lock/Unlock DeviceThe Device can be locked by apply a 4 digit pin. This may be necessary or desirable where the Device is able to be accessed by third parties who may have sufficient knowledge to be able to change settings within the Device or delete stored data. By locking the Device, the Device will not respond to any com-mands until the 4 digit pin is entered again.When the Device is locked a small red locked padlock image will appear in the Device List and Device Details screen.To unlock the Device re-enter the 4 digit pin. To lock the Device once more enter a 4 digit pin again. NOTE: Do not lose or forget the pin since it will not be possible to unlock the Device unless a full reset of the Device occurs.3.11 Change ºC/ºFThis changes to the units of measure for temperature and dew point in the Device. Any other user of the Device will also see the units of measure change.Enter a 4 digit pin to lock the Device. Enter the same 4 digit pin to unlock the Device
Temperature, Humidity & Dew Point Bluetooth Sensor and Logger User Guide 1.203.13 Calibrate Temperature/Calibrate HumidityIt is possible to enter a calibration offset within the Device for either or both of temperature and humidity. Enter the offset (adding - if the offset is a negative number) and pressing Enter.The Device carries its calibration so every user of the Device will see the calibrated values. On a reset of the Device any calibration values are reduced to zero and are effectively removed.3.14 Disable ButtonThe Disable Button feature ensures the Device cannot be accidentally rest by a long button push. This may be necessary or desirable with the Device can be physically reached by third parties or there is a risk of pressure being exerted on the Device.3.15 Set Class IDThis enables a Device to be set with a Class ID representing a number between 0 and 254. This can be used for identifying groups of Devices where the Device name is not sufficient to identify which group a Device belongs to. When the Device’s button is pushed, or it is powered up such as on a change of battery, the Class ID will temporarily become 255 and the cell of the Device in the Device List will turn grey. This enables the De-vice to be easily identified in the app by pressing its button.3.16 Set Advertising FrequencyA Device’s advertising (radio transmission) frequency can be changed to extend the battery life or to make the Device more responsive to commands. NOTE: Shortening a Device’s advertising frequency can have a detrimental affect on its battery life.
